TECHNICAL FIELD
[0002] This application relates to the field of electronic device technologies, and in particular,
to a support, a display assembly and an electronic device.
BACKGROUND
[0003] A flexible display has advantages such as being light, thin, non-fragile, bendable,
and wearable. Therefore, the flexible display is increasingly used in various electronic
devices. However, due to creep performance of materials such as transparent polyimide
(polyimide, PI) and an optical clear adhesive in the flexible display, the flexible
display are prone to arch, wrinkle, and the like. To resolve this problem, a metal
support is usually disposed under the flexible display to support the flexible display.
In addition, a part of a material is hollowed out from a bending portion that is on
the support and that corresponds to the flexible display to form a gap, to reduce
impact of the metal support on bending performance of the flexible display, so that
better dynamic bending performance is implemented. However, when a reliability test
such as a front-side squeezing test or a falling ball test is performed on the flexible
display, a failure problem such as a black spot occurs on the flexible display because
the flexible display is easily squeezed at a position corresponding to the gap of
the support.
SUMMARY
[0004] This application provides a support, a display assembly, and an electronic device,
to ensure that the support can well support a display, while preventing a flexible
display from being squeezed to cause a failure problem.
[0005] According to a first aspect, this application provides a support. The support includes
two support areas and a bending area connected between the two support areas, and
the support may be bent in the bending area. The support includes a hard plate layer,
at least one gap is disposed on a part that is of the hard plate layer and that corresponds
to the bending area, and the gap penetrates a thickness direction of the hard plate
layer. A flexible strip is disposed in each gap, a length direction of the flexible
strip is the same as an extension direction of the gap, and there is a spacing between
the flexible strip and a side wall of the gap in a width direction of the flexible
strip.
[0006] In this application, a flexible strip is disposed in each gap of the hard plate layer,
so that a display also has a support structure at a position corresponding to the
gap of the hard plate layer. This avoids a failure problem such as a black spot that
occurs because the display is easily squeezed at the position corresponding to the
gap of the hard plate layer. In this application, there is a spacing between the flexible
strip and a side wall of the gap in a width direction of the flexible strip, to ensure
that a better support effect for the display is implemented, and ensure that a part
of the bending area of the support can still have relatively good bending performance.
[0007] In some implementations, the support further includes a flexible layer. The hard
plate layer includes a first surface and a second surface that are disposed opposite
to each other in a thickness direction of the hard plate layer. The flexible layer
is located on the first surface of the hard plate layer. The flexible strip is fastened
to the flexible layer. The flexible layer covers at least the bending area.
[0008] The flexible layer is located on the first surface of the hard plate layer, so that
when the display is disposed on the flexible layer, the flexible layer is located
between the display and the hard plate layer. When the display is squeezed at the
position corresponding to the gap of the hard plate layer, the flexible layer can
further support the display and buffer squeeze stress, thereby further protecting
the display, and avoiding a failure problem such as a black spot that occurs because
the display is easily squeezed at a position corresponding to the gap of the support.
In addition, because the flexible layer covers the bending area of the support 32,
a supporting function for the display can be further implemented, so that mold mark,
touch feeling, and the like of the display assembly can be further improved.
[0009] In some implementations, the flexible layer covers the bending area. A thickness
of the hard plate layer located in the bending area is less than a thickness of the
hard plate layer located in the support area. A thickness of the flexible layer is
a difference between the thickness of the hard plate layer located in the bending
area and the thickness of the hard plate layer located in the support area. The flexible
layer covers the bending area, and a surface that is of the flexible layer and that
is away from the flexible strip is coplanar with a part that is of the first surface
and that is located in the support area.
[0010] In some implementations, the flexible layer covers the bending area and the two support
areas. Both the first surface and a surface that is of the flexible layer and that
is away from the flexible strip are smooth surfaces, and the surface that is of the
flexible layer and that is away from the flexible strip is parallel to the first surface.
[0011] In some implementations, an edge of the flexible layer is embedded in the hard plate
layer, so that the flexible layer is more firmly connected to the hard plate layer,
to increase a service life of the support.
[0012] In some implementations, the hard plate layer includes the first surface and the
second surface that are disposed opposite to each other in the thickness direction
of the hard plate layer, and the spacing between the flexible strip and the side wall
of the gap gradually increases in a direction from the first surface to the second
surface, so that when the support is bent in the bending area, the flexible strip
is squeezed relatively evenly by the side wall of the gap at each position in the
thickness direction. In this way, when the support is bent, force is relatively evenly
applied to a part located in the bending area. This helps prolong a service life of
the support.
[0013] In some implementations, a width of the gap is the same at each position in a thickness
direction of the support, and a width of the flexible strip gradually decreases in
the direction from the first surface to the second surface of the hard plate layer.
[0014] In some implementations, a width of the flexible strip is the same at each position
in a thickness direction of the support, and a width of the gap gradually increases
in the direction from the first surface to the second surface of the hard plate layer.
[0015] In some implementations, a width of the gap is the same at each position in a thickness
direction of the support, and the spacing between the flexible strip and the side
wall of the gap is the same at each position in the thickness direction of the support.
[0016] In some implementations, the hard plate layer includes a first surface and a second
surface that are disposed opposite to each other in a thickness direction of the hard
plate layer, and the flexible strip includes a third surface and a fourth surface
that are disposed opposite to each other in a thickness direction. A thickness of
the flexible strip is the same as a thickness of the part that is of the hard plate
layer and that is in the bending area. The third surface of the flexible strip is
coplanar with the first surface of the part that is of the hard plate layer and that
is in the bending area. The fourth surface of the flexible strip is coplanar with
the second surface of the part that is of the hard plate layer and that is in the
bending area, so that the display can be flat when being disposed on the support,
and each position of the support can well support the display.
[0017] In some implementations, both the flexible layer and the flexible strip are made
of a deformable elastic material, to ensure that the support has good support effect
for the display, and has relatively good bending performance. In addition, when the
support is bent, the flexible layer and the flexible strip can generate extrusion
deformation or tensile deformation. While good bending performance is implemented,
a size of the spacing between the flexible strip and the side wall of the gap is reduced
as much as possible, to avoid a failure problem such as a black spot that occurs because
the display is easily squeezed at the position corresponding to the gap of the support.
[0018] In some implementations, a material for making the flexible layer and a material
for making the flexible strip are the same or different, and the flexible layer and
the flexible strip are obtained by using a same process. This simplifies a manufacturing
process and reduces manufacturing costs, and improves firmness of a connection between
the flexible layer and the flexible strip.
[0019] In some implementations, a thickness of the flexible layer ranges from 0.01 mm to
0.05 mm. This ensures that the flexible layer has specific support performance, avoids
impact on bendability of the support, and increases a thickness and a weight of the
support as little as possible.
[0020] In some implementations, a thickness of the hard plate layer ranges from 0.02 mm
to 0.15 mm. This ensures that the hard plate layer has specific support performance,
and increases a thickness and a weight of the support as little as possible.
[0021] In some implementations, a width of the spacing between the flexible strip and the
side wall of the gap in the width direction of the flexible strip ranges from 0.02
mm to 0.2 mm. This ensures that there is a specific spacing between the flexible strip
and the side wall of the gap, so that the bending area of the support has relatively
good bending performance, and avoids a failure problem such as a black spot that occurs
because the display is squeezed at a position corresponding to the spacing due to
an excessively large spacing.
[0022] According to a second aspect, this application provides a display assembly. The display
panel includes a display and the foregoing support. The flexible display is fastened
to the support and is located on a side of the first surface of the hard plate layer.
The display includes two non-bending portions and a bending portion connected between
the two non-bending portions. The bending portion is bendable. The two non-bending
portions are respectively disposed opposite to the two support areas of the support.
The bending portion is disposed opposite to a bending area of the support. The bending
portion is bendable.
[0023] In this application, a flexible strip is disposed in each gap of the hard plate layer.
When the display is disposed on the support, the display also has a support structure
at the position corresponding to the gap of the hard plate layer. This avoids a failure
problem such as a black spot that occurs because the display is easily squeezed at
the position corresponding to the gap of the support, and avoids a problem that occurs
on the display when a reliability test such as a front-side squeezing test or a falling
ball test is performed on a flexible display, so that the display assembly has relatively
high reliability. In addition, in this application, there is a spacing between the
flexible strip and a side wall of the gap in a width direction of the flexible strip,
to ensure that a better support effect for the display is implemented, and ensure
that a part of the bending area of the support can still have relatively good bending
performance, thereby ensuring that the display assembly has relatively high reliability
and also has relatively good bending performance.
[0024] According to a third aspect, this application further provides an electronic device.
The electronic device includes a first housing, a second housing, and the foregoing
display assembly. The two non-bending portions of the display of the display assembly
are respectively fastened to the first housing and the second housing. The first housing
and the second housing may be folded relative to each other to a closed state, or
unfolded relative to each other to an open state. When the first housing and the second
housing are in the closed state, the bending portion and a part that is of the support
and that is in the bending area are bent. Because the display assembly has relatively
high reliability and also has relatively good bending performance, the electronic
device can also have relatively high reliability and can have relatively good bendability.

DESCRIPTION OF EMBODIMENTS
[0026] The following describes technical solutions of embodiments in this application with
reference to accompanying drawings.
[0027] FIG. 1 is a schematic diagram of a structure of an electronic device in an open state
according to an embodiment of this application. An electronic device 100 may be a
tablet computer, a mobile phone, a camera, a personal computer, a notebook computer,
a vehicle-mounted device, or a wearable device. In the embodiment shown in FIG. 1,
descriptions are provided by using an example in which the electronic device 100 is
a mobile phone. For ease of description, as shown in FIG. 1, a width direction of
the electronic device 100 is defined as an X axis. A length direction of the electronic
device 100 is a Y axis. A thickness direction of the electronic device 100 is a Z
axis.
[0028] With reference to FIG. 1, FIG. 2 is a schematic diagram of a structure of the electronic
device shown in FIG. 1 in a closed state.
[0029] The electronic device 100 includes a first housing 10, a second housing 20, and a
display assembly 30. The first housing 10 and the second housing 20 can be unfolded
relative to each other to be in an open state. The first housing 10 and the second
housing 20 can alternatively be folded relative to each other to be in a closed state.
In other words, the first housing 10 and the second housing 20 can be switched between
the closed state and the open state. FIG. 1 shows that the electronic device 100 is
in the open state. FIG. 2 shows that the electronic device 100 is in the closed state.
In this application, an example in which the first housing 10 and the second housing
20 are unfolded and folded relative to an X-axis direction is used for description.
[0030] In addition, the display assembly 30 may be configured to display an image, a text,
a video, and the like. The display assembly 30 includes a first part 34, a second
part 35, and a third part 36 that are sequentially connected. The second part 35 is
connected between the first part 34 and the third part 36. The first part 34, the
second part 35, and the third part 36 are located on a same side of the first housing
10 and the second housing 20. In addition, the first part 34 is fastened to the first
housing 10. The second part 35 is located between the first housing 10 and the second
housing 20. The third part 36 is fastened to the second housing 20. The first part
34, the second part 35, and the third part 36 are arranged in a Y-axis direction.
The second part 35 can be bent along an axis in the X-axis direction.
[0031] It may be understood that, when the electronic device 100 is in the open state, the
first part 34, the second part 35, and the third part 36 are approximately at 180°
(where a slight deviation is allowed, for example, 165°, 177°, or 185°). In this case,
the display assembly 30 has a large continuous display area. In other words, the display
assembly 30 can implement large-screen display. Therefore, user experience is better.
When the electronic device 100 is in the closed state, the display assembly 30 is
folded. Specifically, the second part 35 is bent. The first part 34 and the third
part 36 overlap each other
[0032] In addition, FIG. 2 shows that when the electronic device 100 is in the closed state,
the first housing 10 and the second housing 20 are located between the first part
34 and the third part 36. In other words, the display assembly 30 may be folded outward.
In another implementation, when the electronic device 100 is in the closed state,
the display assembly 30 may be alternatively located between the first housing 10
and the second housing 20. In other words, the display assembly 30 may be folded inward.
[0033] In addition, both FIG. 1 and FIG. 2 show that the electronic device 100 may be folded
once. In another implementation, the electronic device 100 may be alternatively folded
for a plurality of times. Specifically, the electronic device 100 includes more housings
that can rotate relative to each other, and the display assembly includes more parts
that can be folded to each other. For example, in some implementations, the electronic
device 100 may be folded twice. Specifically, compared with the electronic device
100 in FIG. 1 and FIG. 2, the electronic device 100 in this implementation further
includes a third housing. The third housing may be folded relative to the second housing
20. The display assembly 20 further includes a fourth part and a fifth part. The fourth
part is connected between the third part 36 and the fifth part, and the fifth part
is fastened to the third housing. The fourth part may be bent along the axis in the
X-axis direction, so that the third part 36 and the fifth part are folded to each
other, and the third housing is folded relative to the second housing 20.
[0034] It may be understood that the first housing 10 and the second housing 20 have a plurality
of connection relationships, for example, a rotatable connection, a slidable connection,
a rotatable and slidable connection, and a detachable fastening connection. In this
embodiment, an example in which the first housing 10 is rotatably connected to the
second housing 20 is used for description. Refer to FIG. 3 and FIG. 4. FIG. 3 is a
schematic exploded partial view of the electronic device 100 shown in FIG. 1. FIG.
4 is a schematic diagram in which a rotation apparatus of the electronic device 100
shown in FIG. 3 is mounted on the first housing 10 and the second housing 20. The
electronic device 100 further includes a rotation apparatus 40. The rotation apparatus
40 is rotatably connected to the first housing 10 and the second housing 20. The rotation
apparatus 40 enables the first housing 10 and the second housing 20 to rotate relative
to each other for folding or unfolding. The rotation apparatus 40 is located between
the first housing 10 and the second housing 20, and the rotation apparatus 40 is disposed
opposite to the second part 35 of the display assembly 30.
[0035] The rotation apparatus 40 includes a first support 41, a second support 42, and a
third support 43. The second support 42 is located between the first support 41 and
the third support 43. In addition, the first support 41, the second support 42, and
the third support 43 are disposed facing the second part 35 of the display assembly
30.
[0036] In addition, one side of the second support 42 is movably connected to the first
support 41. The other side of the second support 42 is also movably connected to the
third support 43. It may be understood that the movable connection may be a rotatable
connection, a slidable connection, a rotatable and slidable connection, or a detachable
fastening connection. In other words, the first support 41, the second support 42,
and the third support 43 are movable with each other. In addition, one side that is
of the first support 41 and that is away from the second support 42 is rotatably connected
to the first housing 10. One side that is of the third support 43 and that is away
from the second support 42 is rotatably connected to the second housing 20. In this
case, the first support 41, the second support 42, and the third support 43 cooperate
with each other, and the first housing 10 and the second housing 20 can rotate relative
to each other for folding or unfolding.
[0037] It may be understood that, when the electronic device 100 is unfolded to the open
state, the first support 41, the second support 42, and the third support 43 jointly
support the second part 35 of the display assembly 30.
[0038] FIG. 5 is a schematic exploded view of a display assembly of the electronic device
100 shown in FIG. 4. The display assembly 30 includes a display 31 and a support 32.
The display 31 is configured to display an image, a text, a video, and the like. The
display 31 is a flexible display. For example, the display 31 may be an organic light-emitting
diode (organic light-emitting diode, OLED) display, an active-matrix organic light-emitting
diode (active-matrix organic light-emitting diode, AMOLED) display, a mini light-emitting
diode (mini organic light-emitting diode) display, a micro light-emitting diode (micro
organic light-emitting diode) display, a micro organic light-emitting diode (micro
organic light-emitting diode) display, or a quantum dot light-emitting diode (quantum
dot light-emitting diode, QLED) display.
[0039] Refer to FIG. 5, and with reference to FIG. 4, the display 31 includes two non-bending
portions and a bending portion 31b connected between the two non-bending portions.
The two non-bending portions are respectively a first bending portion 31a and a third
bending portion 31c. In other words, the first bending portion 31a, the bending portion
31b, and the third bending portion 31c are sequentially connected. The first bending
portion 31a is a part of the first part 34 of the display assembly 30. The bending
portion 31b is a part of the second part 35. The third bending portion 31c is a part
of the third part 36. The bending portion 31b can be bent.
[0040] FIG. 6 is a schematic diagram of the display assembly 30 of the electronic device
100 shown in FIG. 4 in a closed state. When the electronic device 100 is in the closed
state, the bending portion 31b is bent, the first bending portion 31a and the third
bending portion 31c are disposed facing each other, and the first bending portion
31a and the third bending portion 31c are parallel to each other. FIG. 6 shows that
the bending portion 31b is approximately semi-annular. In another implementation,
the bending portion 31b may also be in a water drop shape or another shape.
[0041] FIG. 7 is a partial schematic sectional diagram of an implementation of a display
assembly of the electronic device 100 shown in FIG. 4 at a line A-A. When the electronic
device 100 is in the open state, the first bending portion 31a, the bending portion
31b, and the third bending portion 31c are approximately at 180° (where a slight deviation
is allowed, for example, 165°, 177°, or 185°).
[0042] Refer to FIG. 7 again. The display 31 may include a rear film 311, a display panel
312, a polarizer (Polarizer, POL) 313, and a protection cover 314 that are sequentially
stacked. In other words, the display panel 312 is located between the rear film 311
and the polarizer 313. The protection cover 314 is fastened to a surface that is of
the polarizer 313 and that is away from the display panel 312. The rear film 311 may
be configured to support the display panel 312. The display panel 312 is configured
to display an image, a video, and the like. The protection cover 314 is configured
to protect the polarizer 313, the display panel 312, and the like.
[0043] In addition, the display 31 further includes an optical clear adhesive 315. The optical
clear adhesive 315 is fastened between the polarizer 313 and the protection cover
314. The optical clear adhesive 315 not only enables display light emitted by the
display panel 312 to propagate outside the electronic device 100, but also improves
flexibility of the display assembly 30.
[0044] In an implementation, the display 31 may be a touchscreen. The display 31 can be
configured to generate a touch signal based on a touch action of a user. For example,
when the user taps an icon of camera software on the display 31, the display 31 can
generate a touch signal based on the tapping action of the user, and transmit the
touch signal to a processor (not shown in the figure) of the electronic device 100.
The processor receives the touch signal, and starts the camera software based on the
touch signal. The processor may be mounted on the first housing 10 (refer to FIG.
4), or may be mounted on the second housing 20 (refer to FIG. 4).
[0045] The display panel 312 may have a touch function. In other words, the display panel
312 has a function of a touch panel. For example, the touch panel is embedded into
a light emitting layer of the display panel 312 by using an on-cell technology. In
another implementation, the display panel 312 may alternatively not have a touch function.
In this case, the display 31 further includes a touch panel (not shown in the figure).
The touch panel may be fastened between the protection cover 314 and the polarizer
313, or may be located between the polarizer 313 and the display panel 312.
[0046] Refer to FIG. 7 again. The display 31 includes an outer surface 316 and an inner
surface 317 that are disposed opposite to each other. The outer surface 316 of the
display 31 is a surface that is of the display 31 and that faces the user when the
user normally uses the electronic device 100. The inner surface 317 of the display
31 is surface that is of the display 31 and that faces the first housing 10 and the
second housing 20 when the display assembly 30 is mounted on the first housing 10
and the second housing 20.
[0047] In addition, the support 32 is fastened to the inner surface 317 of the display 31.
The support 32 is configured to support the display 31, to improve overall strength
of the display assembly 30. In an implementation, the support 32 may be fastened to
the inner surface 317 of the display 31 by using an optical clear adhesive (OCA),
a PVB adhesive, a foam adhesive, a combination thereof, or the like. FIG. 7 shows
that an optical clear adhesive 39 is disposed between the support 32 and the inner
surface 317 of the display 31, to fasten the support 32 and the display 31 by using
the optical clear adhesive 39.
[0048] Refer to FIG. 7 again. In a Z-axis direction, a height H1 of the support 32 ranges
from 0.02 mm to 0.2 mm. In this case, a thickness of the support 32 is moderate, so
that it can be ensured that the support 32 has better rigidity and flexibility, and
the support 32 does not greatly increase a thickness and weight of the display assembly
30. In another embodiment, the height H1 of the support 32 may alternatively be in
another numerical range.
[0049] Refer to FIG. 5 again. The support 32 includes two support areas and a bending area
32b connected between the two support areas. The two support areas are respectively
a first support area 32a and a second support area 32c. In other words, the first
support area 32a, the bending area 32b, and the second support area 32c are sequentially
connected. It should be noted that, for ease of description, the first support area
32a, the bending area 32b, and the second support area 32c divide the support 32 into
three areas, which are not actual structures. In FIG. 5, the first support area 32a,
the bending area 32b, and the second support area 32c are distinguished from each
other by using dashed lines.
[0050] Refer to FIG. 4 and FIG. 5. The two non-bending portions of the display 31 respectively
correspond to the two support areas of the support 32. To be specific, the first bending
portion 31a is disposed opposite to the first support area 32a, the second bending
portion 3183 is disposed opposite to the second support area 32c, and the bending
portion 31b is disposed opposite to the bending area 32b. The support 32 may be bent
at the bending area 32b. In this application, the support 32 is a structure whose
rigidity is greater than that of the display 31, and can support the display 31 to
some extent, to avoid problems such as arching, wrinkle, and collapse of the display
31. In addition, in this application, when a part that is of the support 32 and that
is in the bending area 32b is bent to a same extent as the bending portion 31b of
the display 31, a resilience force of the part that is of the support 32 and that
is in the bending area 32b is greater than a resilience force of the bending portion
31b, so that when the electronic device 100 is in a folded state, the part in the
bending area 32b can also better support the bending portion 31b.
[0051] Refer to FIG. 6 again. When the electronic device 100 is in the closed state, both
the bending area 32b and the bending portion 31b are bent, and a part that is of the
support 32 and that is located in the first support area 32a is parallel to a part
that is of the support 32 and that is located in the second support area 32c. FIG.
6 shows that the support 32 is approximately annular. In another implementation, the
support 32 may also be in a water drop shape or another shape.
[0052] Refer to FIG. 7 again. When the electronic device 100 is in the open state, the part
that is of the support 32 and that is located in the first support area 32a, the part
that is of the support 32 and that is located in the bending area 32b, and the part
that is of the support 32 and that is located in the second support area 32c are approximately
at 180° (where a slight deviation is allowed, for example, 165°, 177°, or 185°). FIG.
7 shows that the part that is of the support 32 and that is located in the first support
area 32a, the part that is of the support 32 and that is located in the bending area
32b, and the part that is of the support 32 and that is located in the second support
area 32c are at 180°.
[0053] Refer to FIG. 7. The support 32 includes a hard plate layer 321. At least one gap
322 is disposed on a part that is of the hard plate layer 321 and that corresponds
to the bending area 32b. The gap 322 penetrates a thickness direction of the hard
plate layer 321. An extension direction of the gap 322 is perpendicular to an arrangement
direction of the two support areas. In this implementation, an arrangement direction
of the first support area 32a and the second support area 32c is a length direction
(a Y-axis direction in FIG. 7) of the electronic device 100. Therefore, the extension
direction of the gap 322 is a width direction of the electronic device 100.
[0054] The hard plate layer 321 includes a first surface 321a and a second surface 321b
that are disposed opposite to each other in the thickness direction (a Z-axis direction
in FIG. 7) of the hard plate layer 321. When the display 31 is disposed on the support
32, the display 31 is located on a side that is of the hard plate layer 321 and that
is close to the first surface 321a. It should be noted that the first surface 321a
of the hard plate layer 321 is all surfaces that are of the hard plate layer 321 and
that face the display 31. For example, when a thickness of a part that is of the hard
plate layer 321 and that is located in the bending area 32b is different from a thickness
of a part that is of the hard plate layer 321 and that is located in the support area,
the first surface 321a of the hard plate layer 321 is jointly formed by a surface
that is of the part that is of the hard plate layer 321 and that is located in the
bending area 32b and that faces the display 31 and a surface that is of the part that
is of the hard plate layer 321 and that is located in support area and that faces
the display 31. In this case, a part that is of the first surface 321a and that is
located in the bending area 32b is not coplanar with a part that is of the first surface
321a and that is located in the support area.
[0055] In this application, the hard plate layer 321 is made of a material with specific
rigidity, so that the support 32 including the hard plate layer 321 has specific rigidity,
to support the display 31. In addition, the hard plate layer 321 needs to have specific
elasticity, to ensure that the display assembly 30 can be bent. Specifically, a material
of the hard plate layer 321 may be metal materials such as copper, aluminum, beryllium
copper, stainless steel, or titanium alloy, or may be a plastic plate with specific
rigidity and elasticity. In this case, the hard plate layer 321 can have better hardness
and rigidity, and has specific elasticity. In some implementations of this application,
a thickness of the hard plate layer 321 ranges from 0.02 mm to 0.15 mm. This ensures
that the hard plate layer 321 has a specific thickness, so that the hard plate layer
321 can meet required rigidity and elasticity, and prevent an excessively large thickness
of the hard plate layer 321 from affecting a thickness and a weight of the display
assembly. It should be noted that thicknesses of the hard plate layer 321 at different
positions may be the same or different as required. The thicknesses of the hard plate
layer 321 at different positions all range from 0.02 mm to 0.15 mm.
[0056] In this implementation, the hard plate layer 321 is an integrated structure, and
may be obtained by cutting an integral plate by using a computer numerical control
(computer numerical control, CNC) processing technology, or may be obtained by using
extrusion molding, injection molding, compression molding, calendering, chemical corrosion,
or the like. In another implementation, a part that is of the hard plate layer 321
and that is in the first support area 32a, a part that is of the hard plate layer
321 and that is in the bending area 32b, and a part that is of the hard plate layer
321 and that is in the second support area 32c may also be separately processed, and
then connected in a welding manner, a snap-fit fastening manner, or the like, to obtain
the hard plate layer 321.
[0057] In this application, at least one gap 322 is disposed on a part that is of the hard
plate layer 321 and that corresponds to the bending area 32b, and an extension direction
of the gap 322 is a width direction of the electronic device 100. Therefore, flexibility
of the hard plate layer 321 located in the bending area 32b can be improved, to further
avoid impact of the hard plate layer 321 on bending performance of the display assembly
30, and improve bendable performance of the display assembly 30. It should be noted
that, in this application, the extension direction of the gap 322 is the width direction
of the electronic device 100, but a slight deviation, for example, 155°, 166°, or
177°, may also be allowed.
[0058] FIG. 8 is a schematic diagram of a partial structure of the hard plate layer 321
according to an implementation of this application. In this implementation, a plurality
of gaps 322 are disposed on the hard plate layer 321, and the plurality of gaps 322
are arranged according to a specific periodic rule. Therefore, rigidity of a part
that is of the hard plate layer 321 and that is located in the bending area 32b can
be ensured, to ensure a support effect for the display 31, and further improve flexibility
of the part that is of the hard plate layer 321 and that is located in the bending
area 32b. Specifically, the part that is of the hard plate layer 321 and that corresponds
to the bending area 32b includes a plurality of columns of gaps 322 disposed in a
direction (a Y-axis direction in FIG. 8) from the first support area 32a to the second
support area 32c, and each column of gaps 322 includes at least one gap 322. When
a same column of gaps 322 includes a plurality of gaps 322, the plurality of gaps
322 located in the same column are arranged in a width direction (an X-axis direction
in FIG. 8) of the electronic device 100. Adjacent columns of gaps 322 are arranged
in a staggered manner. In other words, a direction of a connection line between ends
of the adjacent columns of gaps 322 is different from the Y-axis direction. In some
implementations, the adjacent columns of gaps 322 may alternatively be not staggered.
In other words, the direction of the connection line between the ends of the adjacent
columns of gaps 322 is the same as the Y-axis direction. In this implementation, the
adjacent columns of gaps 322 are arranged in a staggered manner, so that flexibility
of the part that is of the hard plate layer 321 and that is located in the bending
area 32b can be improved, and rigidity of the part that is of the hard plate layer
321 and that is located in the bending area 32b can be retained as much as possible,
to ensure flexibility of the display panel and ensure a support effect for the display
31. It may be understood that, at an edge position of the hard plate layer 321, only
a part of the gap 322 may be disposed due to space limitation. For example, in FIG.
8, a first column of gaps 322 closest to the first support area 32a includes one entire
gap 322 and a half gap 322 located at both ends of the entire gap 322.
[0059] FIG. 9 is an enlarged schematic diagram of a structure of the hard plate layer 321
shown in FIG. 8 at a position B. In the Y-axis direction, a width of a spacing part
between two adjacent columns of gaps 322 is b1. In an implementation, b1 ranges from
0.2 mm to 0.3 mm. For example, b1 is equal to 0.2 mm, 0.22 mm, 0.26 mm, 0.29 mm, or
0.3 mm. In this way, in the Y-axis direction, there is a relatively large quantity
of remaining materials between two adjacent gaps 322, to ensure that the hard plate
layer 321 has better strength.
[0060] Refer to FIG. 9 again. In the X-axis direction, a length b2 of a spacing part between
two adjacent gaps 322 in a same column of gaps 322 ranges from 0.2 mm to 0.6 mm. For
example, b2 is equal to 0.4 mm, 0.44 mm, 0.5 mm, 0.55 mm, or 0.6 mm. In this way,
in the X-axis direction, there is a relatively large quantity of remaining materials
between two adjacent gaps 322, to ensure that the hard plate layer 321 has better
strength.
[0061] A shape of the gap 322 may be randomly designed based on an actual requirement. For
example, in an implementation of FIG. 9, a middle part of the gap 322 is in a rectangular
strip shape, and two ends of the middle part are expanded into a circle, a rectangle
with a width greater than that of the middle part, or another shape, so that the gap
322 is approximately in a dumbbell shape. In some implementations, the gap 322 may
alternatively be directly in shapes such as a rectangular strip shape and an elliptical
strip shape.
[0062] Refer to FIG. 10 and FIG. 7. FIG. 10 is a schematic diagram of a structure of the
bending area 32b of the support 32 at the position B in FIG. 8. A flexible strip 324
is disposed in each gap 322, and a length direction of the flexible strip 324 is the
same as the extension direction of the gap 322, that is, the length direction of the
flexible strip 324 is the width direction (an X-axis direction in FIG. 10) of the
electronic device 100. Both ends in the length direction of the flexible strip 324
may be fastened to the gap 322. Alternatively, in some implementations, the flexible
strip 324 is directly fastened to the display 31 by using the optical clear adhesive
39, to ensure that the flexible strip 324 is fastened relative to the hard plate layer
321. In this application, the flexible strip 324 is disposed in each gap 322, so that
the display 31 also has a support structure at a position corresponding to the gap
322 of the hard plate layer 321. This avoids a failure problem such as a black spot
that occurs because the display 31 is easily squeezed at a position corresponding
to the gap 322 of the support 32.
[0063] In this implementation, the flexible strip 324 includes a third surface 324a and
a fourth surface 324b that are disposed opposite to each other in a thickness direction.
A thickness of the flexible strip 324 is the same as a thickness of the part that
is of the hard plate layer 321 and that is in the bending area 32b. The third surface
324a of the flexible strip 324 is coplanar with the first surface 321a of the part
that is of the hard plate layer 321 and that is in the bending area 32b, so that the
display 31 can remain flat when being disposed on the support 32. In addition, the
fourth surface 324b of the flexible strip 324 is coplanar with the second surface
321b of the part that is of the hard plate layer 321 and that is in the bending area
32b, so that since the support 32 is flattened, a position of the flexible strip 324
is not suspended, and each position of the support 32 can well support the display
31. It may be understood that, due to impact of manufacturing precision of the support
32 or another condition, there may be a small distance between the fourth surface
324b of the flexible strip 324 and the second surface 321b of the part that is of
the hard plate layer 321 and that is in the bending area 32b, or it may be considered
that the fourth surface 324b of the flexible strip 324 are basically coplanar with
the second surface 321b of the part that is of the hard plate layer 321 and that is
in the bending area 32b.
[0064] In this application, there is a spacing 323 between the flexible strip 324 and a
side wall of the gap 322 in a width direction of the flexible strip 324, to ensure
that a better support effect for the display 31 is implemented, and ensure that a
part of the bending area 32b of the support 32 can still have relatively good bending
performance. The width direction of the flexible strip 324 is perpendicular to a length
direction of the flexible strip 324, and is a length direction (a Y-axis direction
in FIG. 10) of the electronic device 100. It should be noted that a material for making
the flexible strip 324 is a deformable elastic material. Therefore, when a part that
is of the support 32 and that corresponds to the bending area 32b is bent, and two
sides in the width direction (the Y-axis direction in FIG. 10) of the flexible strip
324 are squeezed by side walls in a width direction (the Y-axis direction in FIG.
10) of the gap 322, the flexible strip 324 can be compressed and deformed to some
extent. Therefore, a width L1 (that is, a size of the spacing 323 in the Y-axis direction
in FIG. 10) of the spacing 323 may be set to be relatively small. This can meet bending
performance of the support 32, and avoid a failure problem such as a black spot that
occurs because the display 31 is easily squeezed at a position corresponding to the
spacing 323. Specifically, the material for making the flexible strip 324 may be rubber,
foam, thermoplastic polyurethanes (Thermoplastic polyurethanes, TPU), thermoplastic
elastomer (Thermoplastic Elastomer, TPE), or the like.
[0065] In some implementations of this application, the width L1 of the spacing 323 may
range from 0.02 mm to 0.2 mm. It should be noted that, in some implementations of
this application, a shape of the flexible strip 324 may be a structure that is the
same as or different from a shape of the gap 322, and sizes of the spacing 323 between
the flexible strip 324 and the side wall of the gap 322 at different positions may
be the same or different. In an implementation shown in FIG. 9, the flexible strip
324 has a same shape as the gap 322, that is, is of a dumbbell-shaped structure. Therefore,
the sizes of the spacing 323 between the flexible strip 324 and the side wall of the
gap 322 at any position are the same. In some other implementations of this application,
a shape of the flexible strip 324 may be a structure different from a shape of the
gap 322. For example, the gap 322 is in an approximate dumbbell shape, and the flexible
strip 324 is a rectangular strip shape. In this case, the sizes of the spacing 323
between the flexible strip 324 and the side wall of the gap 322 at different positions
are different, but the width D1 of the spacing 323 is still within a specified range,
so that an effect of this application can still be implemented.
[0066] In this application, there is the spacing 323 between the side wall of the gap 322
and both sides of the flexible strip 324 in the width direction, and sizes of the
spacing 323 between the two sides of the flexible strip 324 in the width direction
and the side wall of the gap 322 may be the same or different. In this implementation,
the sizes of the spacing 323 between the two sides of the flexible strip 324 in the
width direction and the side wall of the gap 322 are the same, so that when the display
assembly 30 is bent, squeezing force between the two sides of the flexible strip 324
in the width direction and the side wall of the gap 322 is basically the same. In
this case, force is relatively evenly applied to a part that is of the support 32
and that is located in the bending area 32b. This helps prolong a service life of
the support 32.
[0067] In this implementation, a width of the gap 322 on the hard plate layer 321 is the
same at all locations in the thickness direction (that is, the Z-axis direction in
FIG. 7) of the support 32. In other words, a cross section of the gap 322 in a direction
perpendicular to the extension direction of the gap 322 is a rectangle. The spacing
323 between the flexible strip 324 and the side wall of the gap 322 is the same at
each position in the thickness direction of the support 32. In other words, a cross
section of the flexible strip 324 in a direction perpendicular to the length direction
of the flexible strip 324 is also a rectangle, so that a width of the spacing 323
between the side wall of the gap 322 and both sides of the flexible strip 324 in the
width direction is the same at different positions in the thickness direction (the
Z-axis direction in FIG. 7) of the support 32.
[0068] FIG. 11 is a schematic diagram of a partial structure of the support 32 according
to another implementation of this application. A difference between the support 32
in this implementation and the support 32 in FIG. 7 lies in that the spacing 323 between
the flexible strip 324 and the side wall of the gap 322 gradually increases in a direction
from the first surface 321a to the second surface 321b. Specifically, in this implementation,
the width of the gap 322 is the same at each position in the thickness direction of
the support 32. In other words, a cross section of the gap 322 in a direction perpendicular
to the extension direction of the gap 322 is a rectangle. A width of the flexible
strip 324 gradually decreases in the direction from the first surface 321a to the
second surface 321b of the hard plate layer 321. In other words, a cross section of
the flexible strip 324 in a direction perpendicular to an extension direction of the
flexible strip 324 is a trapezoid, and a width of a side that is of the flexible strip
324 and that is close to the first surface 321a is greater than a width of a side
that is of the flexible strip 324 and that is close to the second surface 321b. In
this case, the spacing 323 between the flexible strip 324 and the side wall of the
gap 322 gradually increases in the direction from the first surface 321a to the second
surface 321b. When the display assembly 30 is folded in an outward folding manner,
the first surface 321a of the support 32 is compressed and deformed to a less extent
than the second surface 321b. In this case, a cross section of the gap 322 of the
support 32 in a direction perpendicular to a length direction of the gap 322 is deformed
from a rectangle to a trapezoid, and an opening that is of the trapezoidal gap 322
and that is located on the first surface 321a is greater than the second surface 321b.
In this implementation, the flexible strip 324 is set to a structure whose width gradually
decreases in the direction from the first surface 321a to the second surface 321b
of the hard plate layer 321, so that when the display assembly is bent, a shape of
the flexible strip 324 is basically the same as a shape of the deformed gap 322. In
this case, the flexible strip 324 can be squeezed relatively evenly by the side wall
of the gap 322 at each position in the thickness direction, and when the support 32
is bent, force is relatively evenly applied to a part located in the bending area
32b. This helps prolong a service life of the support 32.
[0069] FIG. 12 is a schematic diagram of a partial structure of the support 32 according
to another implementation of this application. A difference between the support 32
in this implementation and the support 32 in FIG. 11 lies in that, in this implementation,
the width of the gap 322 gradually increases in the direction from the first surface
321a to the second surface 321b of the hard plate layer 321. In other words, a cross
section of the gap 322 in a direction perpendicular to the extension direction of
the gap 322 is a trapezoid, and an opening that is of the gap 322 and that is located
on the first surface 321a is less than an opening that is of the gap 322 and that
is close to the second surface 321b. The width of the flexible strip 324 is the same
at each position in the thickness direction of the support 32. In other words, a cross
section of the flexible strip 324 in a direction perpendicular to the extension direction
of the flexible strip 324 is a rectangle, so that the spacing 323 between the flexible
strip 324 and the side wall of the gap 322 gradually increases in the direction from
the first surface 321a to the second surface 321b. When the display assembly 30 is
folded in an outward folding manner, the first surface 321a of the support 32 is compressed
and deformed to a less extent than the second surface 321b. In this case, a cross
section of the gap 322 of the support 32 in a direction perpendicular to the length
direction of the gap 322 is deformed from a trapezoid to an approximately rectangular
structure. In this implementation, a cross section of the flexible strip 324 in the
direction perpendicular to the extension direction of the flexible strip 324 is a
rectangular structure, so that when the display assembly is bent, a shape of the flexible
strip 324 is basically the same as a shape of the deformed gap 322. In this case,
the flexible strip 324 can be squeezed relatively evenly by the side wall of the gap
322 at each position in the thickness direction, and when the support 32 is bent,
force is relatively evenly applied to a part located in the bending area 32b. This
helps prolong a service life of the support 32. In addition, because the thickness
of the flexible strip 324 at each position is uniform, support performance of the
flexible strip 324 at each position is even, so that the display 31 can be well supported.
[0070] FIG. 13 is a schematic diagram of a partial structure of the display assembly 30
according to another implementation of this application. A difference between the
support 32 in this implementation and the support 32 in FIG. 10 lies in that, in this
implementation, the support 32 further includes a flexible layer 325. The flexible
layer 325 is located on the first surface 321a of the hard plate layer 321. When the
display 31 is stacked on the support 32, the flexible layer 325 is located between
the display 31 and the support 32. The flexible strip 324 is fastened to the flexible
layer 325, and the flexible layer 325 covers at least the bending area 32b. In other
words, the flexible layer 325 can cover only the bending area 32b of the hard plate
layer 321, or may cover the bending area 32b, the first support area 32a, and the
second support area 32c of the hard plate layer 321.
[0071] In this implementation, the flexible layer 325 can cover only the bending area 32b
of the hard plate layer 321. Specifically, in this implementation, a thickness of
a part that is of the hard plate layer 321 and that is located in the bending area
32b is D1, a thickness of a part that is of the hard plate layer 321 and that is located
in the first support area 32a and the second support area 32c is D2, and D1 is less
than D2. A thickness of the flexible layer 325 is D3, and D3 is a difference between
D2 and D1. To be specific, when the flexible layer 325 covers the bending area 32b
of the hard plate layer 321, a surface that is of the flexible layer 325 and that
is away from the flexible strip 324 is coplanar with a part that is of the first surface
321a and that is located in the support area.
[0072] In this implementation, the flexible layer 325 may also be made of a deformable elastic
material, for example, a rubber material, a foam material, a TPU material, or a TPE
material. The material for making the flexible layer 325 may be the same as the material
for making the flexible strip 324, or may be different from the material for making
the flexible strip 324. In this implementation, both the material for making the flexible
layer 325 and the material for making the flexible strip 324 are rubber materials,
so that a manufacturing process can be further simplified, and the flexible layer
325 is more firmly connected to the flexible strip 324. In some other implementations
of this application, the material for making the flexible layer 325 may alternatively
be different from the material for making the flexible strip 324. For example, in
some implementations, the material for making the flexible layer 325 is foam, and
the material for making the flexible strip 324 is rubber.
[0073] In some implementations, the flexible layer 325 and the flexible strip 324 may be
obtained by using a same process, so that the manufacturing process is further simplified,
and the flexible layer 325 is more firmly connected to the flexible strip 324. Specifically,
the flexible layer 325 and the flexible strip 324 may be integrally formed by using
injection molding, compression molding, calendering, or the like.
[0074] In this implementation, the flexible layer 325 is located between the display 31
and the hard plate layer 321, so that when the display 31 is squeezed at a position
corresponding to the gap 322 of the hard plate layer 321, the flexible layer 325 can
further support the display 31 and buffer squeeze stress, thereby further protecting
the display 31, and avoiding a failure problem such as a black spot that occurs because
the display is easily squeezed at the position corresponding to the gap 322 of the
support 32. In addition, because the flexible layer 325 covers the bending area 32b
of the support 32, a supporting function for the display 31 can be further implemented,
so that mold mark, touch feeling, and the like of the display assembly 30 can be further
improved. Specifically, the flexible layer 325 further supports the display 31, so
that when the display assembly 30 is folded, a contour of the gap 322 of the hard
plate layer 321 is not easily presented on the display 31, to improve mold mark, touch
feeling, and the like of the display assembly 30.
[0075] In this implementation, to enable the flexible layer 325 to well support the display
31, and avoid impact of the flexible layer 325 on bending performance of the display
assembly 30 as much as possible, the thickness D2 of the flexible layer 325 needs
to be within a specific range. In some implementations of this application, the thickness
D3 of the flexible layer 325 ranges from 0.01 mm to 0.05 mm.
[0076] In some implementations of this application, an edge of the flexible layer 325 is
embedded in the hard plate layer 321, so that the flexible layer 325 is more firmly
connected to the hard plate layer 321, to increase a service life of the support 32.
For example, FIG. 14 is a schematic diagram of a partial structure of the support
32 according to another implementation of this application. A difference between this
implementation and the implementation shown in FIG. 12 lies in that, in this implementation,
the flexible layer 325 includes a middle area 325a and edge areas 322b located on
two sides of the middle area 325a, and a thickness of the edge area 322b of the flexible
layer 325 is less than a thickness of the middle area 325a, so that an edge of the
flexible layer 325 forms a stepped structure. A thickness of a part that is of the
hard plate layer 321 and that is located in the bending area 32b is less than a thickness
of a part that is of the hard plate layer 321 and that is located in the first support
area 32a and the second support area 32c. A groove 326 is disposed on a side that
is of the first support area 32a and the second support area 32c and that is close
to the bending area 32b. When the flexible layer 325 is disposed in the bending area
32b of the hard plate layer 321, the edge area 322b of the flexible layer 325 is embedded
in the groove 326 of the first support area 32a and the second support area 32c of
the hard plate layer 321. In addition, a surface that is of the flexible layer 325
and that is away from the flexible strip 324 is coplanar with a part that is of the
first surface 321a of the hard plate layer 321 and that is located in the support
area, to ensure that a surface that is of the support 32 and that faces the display
31 is flat, and ensure that the support 32 well supports the display 31. In this implementation,
the support 32 may be obtained by using injection molding. To be specific, after a
hard plate is first formed in a mold, the flexible layer 325 is formed through molding
again. In this way, the flexible layer 325 and the hard plate part form an integrated
structure, to simplify a manufacturing process, and improve firmness of a connection
between the flexible layer 325 and the hard plate part.
[0077] FIG. 15 is a schematic diagram of a partial structure of the display assembly 30
according to another implementation of this application. A difference between the
support 32 in this implementation and the support 32 in FIG. 13 lies in that, in this
implementation, the bending area 32b, the first support area 32a, and the second support
area 32c of the hard plate have a same thickness. The flexible layer 325 covers the
bending area 32b, the first support area 32a, and the second support area 32c. Both
a surface that is of the flexible layer 325 and that is away from the flexible strip
324 and the first surface 321a of the hard plate layer 321 are smooth surfaces, and
the surface that is of the flexible layer 325 and that is away from the flexible strip
324 is parallel to the first surface that is of the hard plate layer 321 and that
is located in the support area. In this implementation, the flexible layer 325 can
well support the display 31 at each position. In addition, because the flexible layer
325 is made of an elastic material and can provide a buffer for the display 31, when
the display 31 receives impact such as vibration or collision, the flexible layer
325 can have a buffer function, to reduce a risk of damage to the display 31.
